• Performing a fuzzy search may retrieve terms with similar spellings: te sach y nang dau hoi. hieu ve cac ((xuc van) or (((luc van) OR (luu van)))) hang de cua tuc~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach y nang dau hoi. hieu ve cac ((xuc van) OR (((luc van) OR (luu van)))) hang de cua tuc*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach y nang dau hoi. hieu ve cac ((xuc van) or (((luc van) OR (luu van)))) hang de cua tuc*".
